If the worth of a film can be measured in how much it’s managed to invade the public consciousness, Aliens would rank in the Top Three. If you’ve played virtually any game in the last 20 years, there’s a better then likely chance you’ve encountered at least one line or allusion to the film. It’s easily one of the most quotable films of all time. You all know it, you’ve all seen it, and if you hate it, it’s probably because you liked Alien better.

Originally, when the ‘Bambi’ alien crawls out for the first time, they used a whippet covered in foam ‘alien bits’ to try and simulate a more organic alien/dog hybrid. It worked about as well as you can imagine

David Fincher was so angry with the interference he received during the filming of Alien 3, when Fox offered to let him recut the movie however he wished with absolutely no executive meddling for the Alien Quadrilogy DVD boxset, he outright refused.
